1
ER signal sequence
A portion of a protein's amino acid sequence that directs it to the rough endoplasmic reticulum for processing.
New cards
2
Signal Recognition Particle (SRP)
A protein that binds to the ER signal sequence on a nascent protein to facilitate its entry into the endoplasmic reticulum.
New cards
3
Translocon
The channel protein in the endoplasmic reticulum that allows the translocation of polypeptides into the ER lumen.
New cards
4
Cisternae
Flattened membrane-bound compartments found in the Golgi apparatus that are involved in the processing and sorting of proteins.
New cards
5
Receptor-mediated endocytosis
A cellular process by which cells internalize molecules (such as nutrients) using specific transmembrane receptors.
New cards
6
Phagocytosis
The process by which certain cells engulf large particles or microorganisms, forming a phagosome.
New cards
7
Autophagy
A cellular process that degrades damaged or unnecessary cellular components by enclosing them in autophagosomes and delivering them to lysosomes for breakdown.
New cards
8
Actin filaments (microfilaments)
The smallest components of the cytoskeleton, involved in cell shape, structure, and movement.
New cards
9
Intermediate filaments
Cytoskeletal components that provide structural support and resilience to cells, with a diameter between actin filaments and microtubules.
New cards
10
Microtubules
The largest cytoskeletal fibers, hollow tubes essential for vesicle transport and cell division
New cards
11
Myosin
A motor protein that interacts with actin filaments to facilitate muscle contraction and cell movement.
New cards
12
Acid hydrolases
Enzymes found in lysosomes that break down various biomolecules, such as proteins and polysaccharides.
New cards
13
Golgi apparatus
An organelle involved in the modification, sorting, and packaging of proteins and lipids for secretion or delivery to other organelles.
New cards
14
Lysosome
An organelle that contains digestive enzymes to break down waste materials and cellular debris.
New cards
15
Vesicle
A small membrane-bound sac that transports substances within or outside of a cell.
New cards
16
Cargo
Molecules or materials that are packed and transported by vesicles in cellular processes.
New cards
17
Chaperones
Proteins that assist in the proper folding and assembly of other proteins within the endoplasmic reticulum.
New cards
18
Oligosaccharides
Short chains of monosaccharides that are attached to proteins or lipids and play roles in cell signaling and recognition.
